RMTAB(5)RMTAB(5)NAMErmtab - local file system mount statistics
DESCRIPTION
Rmtab resides in directory /etc and contains a record of all clients
that have done remote mounts of file systems from this machine.
Whenever a remote mount is done, an entry is made in the rmtab file of
the machine serving up that file system. Umount removes entries, if of
a remotely mounted file system. Umount -a broadcasts to all servers,
and informs them that they should remove all entries from rmtab created
by the sender of the broadcast message. By placing a umount -a command
in /etc/rc.boot, rmtab tables can be purged of entries made by a
crashed host, which upon rebooting did not remount the same file
systems it had before. The table is a series of lines of the form
hostname:directory
This table is used only to preserve information between crashes, and is
read only by mountd(8) when it starts up. Mountd keeps an in-core
table, which it uses to handle requests from programs like showmount(1)
and shutdown(8).

Although the rmtab table is close to the truth, it is not always 100%
accurate.
